Arresting mechanism/lock for coaxial plug connectors

Abstract

Arresting mechanism for coaxial plug connectors. Balls which sit in radial borings of a protective sleeve are kept in a lock-in position by a circularly bent spring that is locked in an outside surrounding flat groove of the protective sleeve. Only on one end is the slotted band spring secured against rotation in the flat groove by indentations provided in the border of the groove.

What is claimed is: 
     
       1. Arresting mechanism for a coaxial plug connector composed of first and second plug connector halves that can be plugged together, an outside conductor sleeve of the first plug connector half provided with a surrounding groove in a front section on an outside surface thereof and the second plug connector half having a receiving space between an outside rigid protective sleeve and an outside conductor sleeve, into which the front section of the outside conductor sleeve of the first plug connector half can be inserted, at least one ball stored in a stepped radial boring of the protective sleeve being provided such that the ball can snap into the surrounding groove, when the first and second plug connector halves are assembled, comprising: the stepped radial bore of the protective sleeve extending into a surrounding flat groove of the protective sleeve which is open towards the outside of the protective sleeve, and a circularly bent band spring contained in this flat groove, the band spring supporting itself at the ball and being interrupted at one location, the band spring being fastened in the flat groove only by means of two opposed indentations in opposite edges, respectively, of a border of the flat groove, the two opposed indentations being at the same circumferential location at one end of the band spring, and the one location of the interruption in the band spring being positioned in the flat groove relative to a location of the stepped radial bore and the indentations in the border of the flat groove being positioned relative to the location of the stepped radial bore such that a certain desired force is applied to the ball stored in the stepped radial bore.   
     
     
       2. Arresting mechanism for a coaxial plug connector composed of first and second plug connector halves, an outside conductor sleeve of the first plug connector half provided with a surrounding groove on an outside surface of a front section thereof and the second plug connector half having a receiving space between an outside rigid protective sleeve and an outside conductor sleeve, into which the front section of the outside conductor sleeve of the first plug connector half can be inserted, at least one stepped radial boring having a ball positioned therein and located in the protective sleeve such that the ball can snap into the surrounding groove, when the first and second plug connector halves are assembled, comprising: an outer opening of the stepped radial bore of the protective sleeve interfacing with a circumferentially surrounding flat groove on an outer surface of the protective sleeve and a circularly bent band spring contained in the flat groove, the band spring supporting itself at the ball and being interrupted at one location, and the band spring being fastened in the flat groove by means of only two opposed indentations in opposite edges, respectively, of a border of the flat groove, the two opposed indentations being at the same circumferential location at one end of the band spring, and the one location of the interruption in the band spring being positioned in the flat groove relative to a location of the stepped radial bore and the indentations in the border of the flat groove being positioned relative to the location of the stepped radial bore such that a certain desired force is applied to the ball stored in the stepped radial bore.   
     
     
       3. Arresting mechanism for a coaxial plug connector composed of first and second plug connector halves, an outside conductor sleeve of the first plug connector half provided with a surrounding groove on an outside surface of a front section thereof and the second plug connector half having a receiving space between an outside rigid protective sleeve and an outside conductor sleeve, into which the front section of the outside conductor sleeve of the first plug connector half can be inserted, at least one stepped radial boring having a ball stored therein and located in the protective sleeve, the ball engaging the surrounding groove, when the first and second plug connector halves are assembled, comprising: an outer opening of the stepped radial bore of the protective sleeve extending into an outward surrounding flat groove of the protective sleeve, and a band spring located in the flat groove, the band spring contacting the ball and being interrupted at one location, the band spring being fastened in the flat groove only by means of two opposed indentations in opposite edges, respectively, of a border of the flat groove, the two opposed indentations being at the same circumferential location at one end of the band spring, and the one location of the interruption in the band spring being positioned in the flat groove relative to a location of the stepped radial bore and the indentations in the border of the flat groove being positioned relative to the location of the stepped radial bore such that a certain desired force is applied to the ball stored in the stepped radial bore.   
     
     
       4. Arresting mechanism for a coaxial plug connector composed of first and second plug connector halves that can be plugged together, an outside conductor sleeve of the first plug connector half provided with a surrounding groove in a front section on an outside surface thereof and the second plug connector half having a receiving space between an outside rigid protective sleeve and an outside conductor sleeve, into which the front section of the outside conductor sleeve of the first plug connector half can be inserted, at least one ball stored in a stepped radial bore of the protective sleeve being provided such that the ball can snap into the surrounding groove, when the first and second plug connector halves are assembled, the stepped radial bore of the protective sleeve extending into a surrounding flat groove of the protective sleeve which is open toward the outside of the protective sleeve, and a circularly bent band spring contained in this flat groove, the band spring supporting itself at the ball and being interrupted at one location, comprising: the band spring being fastened in the flat groove only by means of two opposed indentations in opposite edges, respectively, of a border of the flat groove; and the two opposed indentations being at the same circumferential location at one end of the band spring. 
     
     
       5. Arresting mechanism according to claim 4, wherein the one location of the interruption in the band spring is positioned in the flat groove relative to a location of the stepped radial bore and the indentations in the border of the flat groove are positioned relative to the location of the stepped radial bore such that a certain desired force is applied to the ball stored in the stepped radial bore.
